Analysis of total harmonic distortion in single-phase single-stage grid-connected photovoltaic system

<p>This study presents the power quality issue mainly focus effect of total harmonic distortion (THD) on a grid-connected PV system. Firstly, system with single-phase single-stage has been developed to monitor output values voltage and current also its behaviours. Maximum point tracking (MPPT) was implemented since it is proven as first step for THD reduction because MPPT will extract maximum power, voltage, without fluctuation which leads low level. Furthermore, employment good filter reduces level in Thus, this analysis resolve problems The result shows that value current, <em>I<sub>THD</sub></em> more significant than <em>V<sub>THD</sub></em> case systems operating under different solar irradiances. In conclusion, increase irradiance rated generated thus, increasing performance values.</p>
